Question

Na + Cl2 ------> ?what will be formed? ​

Answer 1

Answer:

2Na + Cl2 ------> 2NaCl

sodium + chlorine = sodium chloride (salt)

Answer 2

Answer:

Sodium chloride NaCl

Explanation:

NaCl will form.

2Na + Cl2 ----> 2NaCl

Each Na atom donates 1 electron from its outermost shell electron to each chlroine atom, so that Na can attain full outermost shell electrons (octet), where it is most stable. Na+ ion is formed after losing 1 electron.

Each chlroine atom gains 1 electron so that it can have 8 outermost shell electrons (stable). It becomes Cl- ion.

Combining Na+ and Cl-, NaCl is formed so that the net charge is 0. To balance the equation, since chlorine exists as diatomic molecule, 2 Na atom reacts with 1 chlorine molecule (2 chlorine atoms) to form 2 NaCl.
